| Medium： | ATCC® Medium 712: PYG w/ Additives |
| Growth Conditions： | Temperature: 25.0°C Duration: axenic Protocol: ATCCNO: 30010 SPEC: This strain is distributed as a freeze-dried preparation. See the general procedures for opening a freeze-dried vial. Aseptically add 0.5 ml of ice cold medium containing 12% (w/v) sucrose to the freeze-dried inner shell vial. Once the culture is completely rehydrated, aseptically add 1 ml of ATCC medium 712 and distribute to a 16 X 125 mm plastic screw-capped test tube or a T-25 tissue culture flask containing 5.0 ml of the same medium. Incubate the test tube culture horizontally with the cap on tight. Trophozoites should be evident in 1-5 days. |
| Subcultivation： | Protocol: ATCCNO: 30010 SPEC: This strain is distributed as a freeze-dried preparation. See the general procedures for opening a freeze-dried vial.

Incubate the test tube culture horizontally with the cap on tight. Trophozoites should be evident in 1-5 days. |
| Cryopreservation： | 1.xa0xa0 To achieve the best results set up cultures with several different inocula (e.g. 0.25 ml, 0.5 ml, 1.0 ml).xa0 Harvest cultures and pool when the culture that received the lowest inoculum is at or near peak density. 2.xa0 If the cell concentration exceeds the required level do not centrifuge, but adjust the concentration to between 2 x 106 and 2 x 107cysts/ml with fresh medium.xa0 If the concentration is too low, centrifuge at 600 x g for 5 min and resuspend the pellet in the volume of fresh medium required to yield the desired concentration. 3.xa0 While cells are centrifuging prepare a 15% (v/v) solution of sterile DMSO as follows:xa0 Add the required volume of DMSO to a glass screw-capped test tube and place it in an ice bath.xa0 Allow the DMSO to solidify.xa0 Add the required volume of refrigerated medium.xa0 Dissolve the DMSO by inverting the tube several times.xa0 xa0xa0xa0xa0xa0 *NOTE: If the DMSO solution is not prepared on ice, an exothermic reaction will occur that may precipitate certain components of the medium. 4.xa0 Mix the cell preparation and the DMSO in equal portions. Thus, the final concentration will be between 106 and 107 cells/ml and 7.5% (v/v) DMSO. The time from the mixing of the cell preparation and DMSO stock solution before the freezing process is begun should be no less than 15 min and no longer than 30 min. 5.xa0xa0 Dispense in 0.5 ml aliquots into 1.0 - 2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation). 6.xa0xa0 Place the vials in a controlled rate freezing unit.xa0 From room temperature cool at -1°C/min to -40°C.xa0 If the freezing unit can compensate for the heat of fusion, maintain rate atxa0xa0xa0xa0xa0xa0xa0 -1°C/min through the heat of fusion.xa0 At -40°C plunge into liquid nitrogen. Alternatively, place the vials in a Nalgene 1°C freezing apparatus.xa0 Place the apparatus at -80°C for 1.5 to 2 hours and then plunge ampules into liquid nitrogen.xa0 (The cooling rate in this apparatus is approximately xa0xa0xa0xa0xa0 -1°C/min.) xa0 7. The frozen preparations are stored in either the vapor or liquid phase of a nitrogen freezer. 8.xa0xa0 To establish a culture from the frozen state place an ampule in a water bath set at 35°C (2-3 min). Immerse the vial just sufficient to cover the frozen material. Do not agitate the vial. 9.xa0xa0 Immediately after thawing, aseptically remove the contents of the ampule and inoculate into 5 ml of fresh ATCC medium 712 in a T-25 tissue culture flask or plastic 16 x 125 mm screw-capped test tube.xa0 Incubate at 25°C. |
